Per the recent discussion comparing D with Lua, tests suggest that iota

Do you agree with making iota for floating-point types a forward range?

I had thought the major slowdown was using code like 'start + step * i' as
opposed to 'current += step', which, although much faster is fundamentally
broken, as with floating point numbers x = (x+1), etc. Am I mistaken?
